Qi Language, documentation, and tests.

This update is focused on use with Steel Bank Common Lisp

Qi 9.2 files were originally migrated from: https://code.google.com/archive/p/qilang/downloads.

Compilable with SBCL 1.5.5 by running "install.txt" through an sbcl session.
 
Qi can then be run from the commandline as so:  "sbcl --core Qi.core"

Many warnings are generated by sbcl during Qi operation. Note, not fully tested.
